The haze value change ( ⁇ Hz) was over 3%, and the antifouling property was poor. In Example 13, the haze value (Hz) after the soil adhesion test (2) was performed was over 5%, and it was confirmed that the soil resistance was poor. In Examples 15 and 16, in which the tin oxide film was hardly formed on the surface of the plate glass and Ra was less than 1 nm, the change in haze value ( ⁇ Hz) before and after the soil adhesion test (1) was more than 3%. Dirty.
  • Example 17 and 19 using a commercially available Low-E glass in which a tin oxide film is formed on one main surface of a plate glass the emissivity is small because the film thickness of the tin oxide film is more than 150 nm. Since it becomes less than 3, when the main surface on the side where the tin oxide film is formed is used as the outdoor side, the heat shielding property is deteriorated.
  • Example 18 using a commercially available Low-E glass in which a tin oxide film was formed on one main surface of a plate glass PV / Ra on the film surface exceeded 15; therefore, before and after the soil adhesion test (1) was performed. The haze value change ( ⁇ Hz) was over 3%, the haze value (Hz) after the soil adhesion test (2) was over 5%, and the antifouling property was poor.
  • excellent antifouling properties can be imparted at low cost.

Abstract

L'invention concerne un article en verre qui permet d'appliquer d'excellentes propriétés antisalissure à faible coût. L'article en verre comprend un film d'oxyde d'étain formée sur l'une des surfaces principales d'une plaque de verre, et est caractérisé en ce que le film d'oxyde d'étain présente une épaisseur de 10 à 150 nm, une rugosité moyenne arithmétique Ra de la surface de film de 1 à 13 nm, et un rapport (PV/Ra) entre la valeur pic-vallée (valeur PV) et Ra de la surface du film de 15 ou moins.
